Satiated Rick lay back between the girls who had begun to doze against him. As much as he wanted to sleep he also wanted to check on Laura.
Extricating himself from the two sleeping girls Rick made his way into the other room. He thought about putting on some clothing then realized how funny that idea seemed with all that had gone on tonight.
As he passed the kitchen clock he noticed that it was five in the morning and almost dawn. From the other room Rick heard the plaintive weeping of two women coming from the living room.
Turning the corner he was greeted by the sight of Laura and the transsexual, Sheila, kneeling doggie style with their asses pressed together. Rick was able to see Sheila's long cock joining them together.
Both women had their eyes shut and, between ragged panting, wept in ecstasy. Rick watched as Laura shook and her abdomen contracted in orgasm. Past the point of control, they were entranced by the intense sexual sensations.
Rick doubted their ability to consciously break their coupling believing they would continue until one was no longer able to stay upright.
"It is amazing, is it not?" Rick was startled by Jon, not realizing he was there.
"They have been like that for almost ten minutes but I do not think they will last much longer." Rick watched as Laura let out a long plaintive wail and collapsed onto the rug.
Cum was still weakly flowing from Sheila's cock as she too succumbed to fatigue. Both creatures continued to shiver in reaction to their intense mating.
"They will be fine in a few minutes." Jon said sensing Rick's concern. "We have a few things to discuss before dawn and that leaves us only a few minutes with which to do it in."
Rick sat across from the strange man. "I am aware that Tracy told you some more about the genetic effects we have on others. But what she did not tell you is that their effects carry on through our contacts almost like a virus." Jon gestured between Rick and Laura.
"You pass on the changes to some one like her, she passes them on to her next partner and so on." Laura crawled up beside Rick and laid her head on his thigh. Across from them Sheila was joining Jon sitting next to him.
"We are not quite as we seem I'm afraid." Rick watched in astonishment as the two stranger's faces seemed to cloud and change. Before him their faces altered to look not quite so human.
They both had large dark eyes, although not black it was difficult to make out pupils. Their faces flattened out somewhat and their whole face seemed to elongate.
When they were finished the two visitors looked like a half-breed, part human part creature. Somehow this didn't shock Rick as much as it might otherwise. Perhaps he was too tired to care or perhaps somewhere in the back of his mind he knew the truth already.
Jon glanced out the window at the brightening sky. "Are there any pressing questions that you have at this time Rick?"
Too tired to even think about it Rick quipped. "Do I have to do any ugly fat broads?" Truthfully he didn't really need an answer.
"Only if you wish to. You can engage any woman you wish to, the rest will take care of itself." Jon rose and stepped towards the back door.
"We will be in touch. I recommend you get some rest I think you are going to need your sleep." With that Jon and Sheila left through the back door. Not even caring where they went Rick took Laura's hand and stumbled back to the bedroom.
Tracy and Janet slept snuggled together on the big bed. Rick lay down next to them and curled up with Laura in his arms.
Rick slept through most of the next day awaking only several times. One time when he rolled over he managed to stay awake long enough to watch his sister Janet and the proverbial 'girl next door', Tracy, between each other's legs barely muffling their cries.
Later he drifted in and out of sleep while Laura, the woman who had taken him in, sucked on his long cock. He awoke again to find her holding his massive erection while Janet, her daughter, slid along its length punctuating the quiet with her gasps. Rick didn't even recall cumming but he awoke once more to find the warm soft body of Janet asleep on his chest still holding his softening cock in her tight pussy.
As he slept, the events of the previous evening went through his head, from the alien visitors to finding out that he'd been genetically altered. Had Rick not seen the events with his own eyes he would never have believed he would help change mankind's genetics and that he'd be starting with his own adoptive family.
He would have laughed at the very suggestion that he would have had voracious sex multiple times with his sister last night. But it was all true. Rick's life had been picked up and stuffed in a blender last night but he seemed to come out ahead of things.
Awaking after everyone else Rick trudged into the shower quickly soaping up and washing his hair. After he stepped out to dry himself Tracy bounced into the room in her usual perky manner.
"Morning sleepy head, we've been at it for hours already." Tracy emphasized 'at it' with a sly grin suggesting that it wasn't spring cleaning they were at.
Tracy was dressed only in a silk robe that clung to her curvaceous body. He was reminded of how she looked last night as she rode him to multiple orgasms.
Apparently his body remembered too, his cock slowly began to grow and he could feel his senses come aware of her sex. This change wasn't lost on Tracy as she glanced down at his expanding organ. "Don't start that, we'll never get anything done if we stay in here and fuck all day."
"Is that so bad?" Rick asked as he put his arms around her soft body.
"It wouldn't be except we have a party tonight, and you'll be the main attraction. Here, put this on and come here." She tossed him his robe and headed off down the hallway...
